matter, etc., the motor obtaining current from an overhead conductor wire by means of a trolley wheel running thereon.-

The invention relates more particularly to the truck hereinbefore mentioned, and its.

object is to provide a novel and improved structure having certain advantages which will be pointed out hereinafter.

In order thatthe invention may be better understood, reference is had to the accompanying drawings forming apart of this In the drawings, p v Figure 1 is an elevation of the apparatus;

Fig.2 is a plan view of the. motor truck;

Fig. 3 is anend View thereof; and I Fig. 4 is a sectional detail of-a bearing. Referring, specifically .tothe drawings,

10 denotes a caror receptacle in which the,

mail matter, merchandise or other commodities to be transported are deposited. This receptacle is supported at each end by a truck provided' with two grooved wheels .11

which run. on an elevated cable track 12,

the supports of which latter have not been illustrated. The receptacle hangs between the two trucks. One of the trucks is propelled by an electric motor, and this may be the truck at either end of the receptacle. The construction of the vtwo trucks is the same, with the exception that certain additional elements are provided for themotor truck. V

The motor is housed in a casing 13 positioned opposite one end of the receptacle 10, and from the casing projects the shaft'14 of the motor, the projecting end of the shaft being equipped with a pulley 14. On shafts 15 of the wheels 11' of the motor truck are pulleys 16. A drive belt 17 passes around these pulleys and also over an idler 18, whereby the motion of the motor shaft Specification of Letterslatent.

is transmittedto the truck wheels, andthe apparatus is propelled along the track 12.

The receptacle is suspended from the trucks by a pairof laterally spaced angle lrons 19, and two angle irons 20 positioned on opposite sides thereof. These angle irons are rigidly fastened to the top of the re-,

ceptacle 10 and they project fromthe end thereof; The angle irons 19 extend in the direction of the length of the receptacle, and the angle irons 20 are positioned obliquely to converge in the direction 'oftheir outer ends. 7

Beyond theend of the receptacle 10, the angle irons 19 and 20 are connected bya cross strip 21, the parts being rivetedor bolted together.' The angle irons 19 ex-' tend. beyond the angle irons 20" and their outerends are connected by 'a cross strip 22,

positioned above the motor housing 13'.

On top of the motor housing 13 isriveted, bolted, or otherwise fastened a heavyrein forcing plate 23, and ontop of the latter are mounted two plates 24: and 25 the same being vertically spaced by spacer strips 26.

At one end of the plate 2 1, the latter has an upright extension 27, --and the correspondingend of the plate 25 has a similar ex-' tension 28. The spacer strips26'have up;

ward-extensions 29 at one end seating be-' tween the parts 27 and 28 and spacing the same laterally.

The plate 2% is riveted orf otherwis e fastened to the plate 23, as shown at 30, and the plate 25 is also secured to the plate 23, the fasteners 31 also passing through the spacer strips 26 and the plate 24.

A stud 32 carried by the plate 23 passes through the plates 24 and 25, and also through an aperturein the cross strip 22. This stud serves as kingzbolt to permit the motor truck to turn, and allow it free play in following the track 12, independent of the receptacle '10.

V The spacer strip extensions 29 seat between the parts 27 and 28, and at the top, the latter support a horizontal bar 34 seating therebetween and extending in the direction of thelength of the, truck. The bar 34 is riveted, bolted, or otherwise fastened to the parts 27 and 28 and projects forwardly and rearwardly therefrom. The part 28 is reinforced at its ends by short strips 35 placed against its Jouterflface, against which strips is placed and secured a bar 36 extending parallel to the'bar 34.

' horizontal apertures t 'seatbearings 38 for At their ends, the bars3 l and 36' are spaced by strips 37 The parts 34, 36 and 37 have V the shafts 15 of the Wheels 11 and their puli y the bearing 38.

leys 16, and these parts also carry angle bracket members 39 supporting a trolleypole mount which has-not been illustrated as it is the subject matter of another application.

The bearings 38 are particularly constructed to hold the parts 34, 36 and 37 firmly'together. As noted in Fig. 4, these parts seat in a reduced portion of the bear ing which is originally of a length to project slightly from the outer face of the part 34. The latter is countersunk around the bearing, and the bearing is spread by hammering, as shown at 4:0 to firmly secure the parts. The same method is used for securing a ball bearing 41 011 the opposite end of It will be noted that the wheels 11 and the pivot 32 of the motor truck coincide with the longitudinal center line of the receptacle 10, so that a perfect balance is obtained. The motor in the casing 13 can be positioned therein to balance the truck and also counter balance the wheel-supporting .frame which is mostly on one side of the wheels.

I claim: 7 1. A carrier for overhead transportation systems, comprising a receptacle, a motor support, a frame extending from the end of the receptacle onto the latter, said support having an upright frame, and drive wheels carried by said upright frame.

2. A carrier for overhead transportation s stems com BS1110 a ,rece tacle a motor support, aframe extending from the end of the receptacle onto the'motor support for a pivotal connection therewith, said support having an upright frame, and drive wheels carried by said uprightframe.

3. A carrier for overhead transportation systems, comprising a receptacle, a motor support, a frame extending from the end of the receptacle onto the latter, said support having an upright frame, and drivewheels carried by said upright frame and coinciding with the longitudinal center line of the receptacle. I I y v 4-. A motor carriage for overhead trans portation systems comprising a motor housing; vertically spaced plates laid on the housing and spaced by separator'bars, the

plates and bars being rigidly secured to the housin vertical extensions of the slates and bars at one end to receive a head comprised of parallel horizontal bars; spacing plates between the ends of said last meniJlOIlGtl, bars; bearings fitted within said ends and spacing plates; and an axle in each bearing adapted to .carrya drive pulley at plates between the ends of said last men-- tioned bars; bearings fitted within'said ends overhead trans and spacingplates, the outer ends-of said bearings being spread and sunk into the outer faces of the bars with which associated, and an axle in each bearing adapted to, carry a drive pulley at one endand a traction wheel at the other end, i. p r In testimony whereof I a'flix my signature.
